FARMINGTON — Police say no charges are forthcoming in a one-vehicle accident involving a pedestrian Thursday night along Route 11 and an investigation is still under way regarding a second accident with four vehicles that occurred shortly after the first.

Farmington Police Sgt. Michael McNeil said an Alton woman driving an SUV who struck a Rochester woman tending to her broken down vehicle on the side of Route 11 will not be charged. Police believe at this time, the injured pedestrian — Brenda Fields, 38, of Rochester — parked too close to the road near Pike Industries and was standing in the roadway when a vehicle driven by Tiffany Bisson, 29, struck her. Fields was also reportedly wearing dark clothing at the time of the crash and did not have hazard lights flashing on her car. Fields was transported to Frisbie Memorial Hospital with serious injuries that were not life-threatening.

The investigation into the crash is still ongoing, McNeil noted, as police continue to process evidence from the scene.

“I think clearly this is just an accident,” he said.

In the second crash reported about 30 minutes after the pedestrian incident at 5:10 p.m., McNeil said it appears a 69-year-old man operating a pickup truck did not notice traffic halting for the first accident, and he subsequently crashed into the vehicle in front of him, creating a “chain reaction.” The incident involved three other vehicles. No injuries were reported but vehicles were damaged and one was towed from the scene.

Paul Dwyer, 69, of Alton, was driving the pickup that crashed into the others, McNeil said.
